A Lake County judge agreed this morning to delay the arraignment of 17-year-old Jeremy Betancourt, who is charged with aggravated street racing and reckless homicide in the death of an Antioch teen, while Betancourt is treated for substance abuse and depression.

Betancourt, also of Antioch, was admitted Friday to a facility where he will spend the next 45 days being treated for “chemical dependency and psychological issues, including depression,” said his lawyer, Jed Stone, after this morning’s hearing.

Betancourt's new arraignment date was set for Sept. 25 by Judge Theodore Potkonjak.

Betancourt was allegedly racing another car when he lost control and crashed in Gurnee on June 24. One of his passengers, Cynthia Perez, 16, was ejected from the back seat of the car after it flipped into a median ditch, officials said.

The driver of the other car, Michael Dawson, 19, of Antioch, was also charged with aggravated street racing. He is represented by a public defender.

“This case is a tragedy for everyone,” Stone said after the hearing. “The family of Cynthia has lost their daughter and Mr. Betancourt’s life is forever changed. There are no winners, only losers in this case. The question is what we should do with a 17-year-old who was drag-racing and had an accident.”
